HYDROCARBON-BURNER.

Specification of Letters Patent.

Application filed November 16, 1911. Serial No. 660,638.

i To all whom it may concern tank is hermetically sealed and provided Beit known that I, JORGEN M. HANSEN, a citizen of the United. States,residing at North Chicago, in the county of Lake and State of Illinois,have invented a new and useful I-IydrocarbomBurner, of which thefollowing is a specification. j

This invention has reference to improvements in hydrocarbonburners andparticularly to a burner which may be fed with fuel by means ofcompressed air or steam.

The object of the invention is to compact and simplify the burner andthe container for fuel, whereby the structure may be made in the form ofa compact portable unit.

The invention as particularly set out in the appended claims will bereadily understood from the following detail description based upon andtaken in connection with the accompanying illustrative drawings,wherein:

Figure 1 shows thepreferred embodiment of, the invention in centralvertical section.

Fig. 5 is alongitudinal section through the jet device. Fig. 6 is a side elevationpartly in vertical section of the same device from adifferent:viewpoint. Fig. 7 shows in elevation one of the valvesof the jet device.Fig. 8 is an end view of the other valve of the jet device, showing theoperating disk. Fig. 9 is a fragmentary view, showing a modified form oftheretort.

The complete furnace illustrated as embodying the invention comprises atank 1,

constituting a joint reservoir for the water 2, the oil 3 and air 4 thelatter being introduced under pressure at 5-by means ofan air pump orother suitable pressure device. Asight gage 6 is arranged in the lowerportion of the tank in order to indicate thedividing line between thewater and oil. This with a pressure gage 7 by means of which thepressure therein/can be readily determined. I

7 Upon suitable standards 8 extending upwardly from the tank issupporteda drum 9 open below and closed above by the domeshaped cover 10,havingacentrally arranged annular upstanding flange 11 to which is bolted orotherwise suitably secured the flue 12, which depends therefromcentrally with-- in the drum 9. This fine, which is open above andbelow, supports in itslower end a Patented Jan. 7, 1913.

retort 13, which comprises a thimble 14 divided by a transverse web. 15and provided with diametrically arranged bosses 16. Each end of thethimble is threaded as at 17, for

engagement with the interior threads of top and bottom cover plates 18and 19, these plates having marginal flanges 20 and 21, which overlie anannular flange 22, which surrounds the thimble midway of its length andof which the bosses 16 are-radial 6X:

tensions. Gaskets 23 and 24 are arranged between themarginalflanges'20-and 21 and the annular flange to effect a tightclosure,

when the cover plates are screwed down by means of polygonal projections25- and 26. Beneath the retort is disposed a burner 27, of any suitableshape though shown in the form of a bar or pipe, closed at each end,and'provided with apertures preferably in i the shape .of transverseslots 28, spaced'" apart along one face of the burner. About the centralportion of ,the burner is arranged a fuel inlet 29, whiohmay be formedintegral therewith or threaded into the same as illustrated. This fuelinlet hasde-- pending inwardly converging walls 30, pro-* vided withslots 31for the admission of ex.

traneous air, thus forming a mixing cham- ,ber. Upon theoppositeside ofthe burner co-axial with the fuelinlet is' a larger. gas

orifice 32, controlled by: the valvej83 carried by the stem 34. v,

The fuel inlet 29 of the burner is arranged to receive the upper end ofa jet'device 35,

comprising a casing 36 provided with the,

central longitudinal bore 37 having an interiorly threaded portion'38and an enlargementor chamber 89,, and also interiorly threaded at 40.YTheforwaidend 0f the casing is reduced at 41 forminga shoulder 42 andexteriorly threaded at 43. to receive the interiorly threaded cap44,havingga central opening 45 corresponding co-axially withthe boreofthecasing. The inner face of this cap is coned at 46 to receive thecorrespondingly exteriorly coned end 47 .of a

valve 48, said valve being exteriorly threaded at49 for engagement withthe threads38 to provide for longitudinal adjustment of the valve withinsaid casing. The valve 48 is provided with spaced grooves 48 extendinglongitudinally of the head 4-7 and connecting the annular space at 37(Fig. 6) with the opening 45 when the valve is unseated. The casing 36is also provided with a nipple 50 and with a radial bore 51 eX- tendingtherethrough into communication with the interior bore 37, said nipplebeing screw threaded to effect a coupling to the supply pipe, as will behereafter described. The valve 48 is likewise provided with an axialbore 52, alining with the opening 45 of the cap. This bore is enlargedto form an interior chamber at 53, which is in communication throughradial ports 54 with the chamber 39 formed by the enlargement in thebore of the casing previously referred to. This chamber is also providedwith a radial channel 55, passing through the wall of the casing and thenipple 56 and also threaded similarly to the nipple 50 for the receptionof a coupling.

The valve 57 is disposed within the chamber 53 to seat upon the bore 52and control the same, said valve having its stem in threaded engagementwith the first valve at 58 for longitudinal adjustment relative thereto.Packing glands 59 and 60 are disposed about the valve stems, one inthread ed engagement with the casing at 40 and the other threaded intothe stem of the first valve at 61. The outer valve member 48 is providedwith an operating wheel 62, formed as a crown pinion with teeth 63 inits face in mesh with the teeth 64 of a pinion 65, mounted upon theoperating shaft 66 journaled between the two forks 67 and 68 of thebifurcated arm, 69, formed integral with the casing 36. The stem 70 ofthe inner valve is provided with a hand wheel 71 in which are formedperipheral sockets 7 2 for the reception of a pin 73', which projectsbetween the forks 67 and 68 and is guided thereby for axial movementwhile angular movement of the same is prevented.

The water pipe 74 extends from the lower part of the reservoir upwardlyand dis charges into the right hand side of the upper chamber 75 of theretort. This water pipe is provided with a manually operable valve 76and a checkvalve 77.

An oil pipe 78 extends from the oil space of the reservoir upwardly anddischarges at the bottom of the lower chamber 7 9 of the retort, thispipe being provided with a manually operable valve 80 and a check valve81. A steam pipe 82 extends from the upper part of the chamber 75downwardly to a point opposite the jet device to a T 83, and thencethrough the pipe 84 coupled to the nipple 56 into the chamber 39 of thejet device. An air pipe 85 provided with a manually operable valve 86extends from the upper portion of the air space of the reservoir to theT 83, whence the air is also conducted by means of the pipe 84 to thechamber 39. The gas pipe 87 leads from the upper portion of the retortchamber 79 to a coupling with the nipple 50, and thence by the channel51 to the interior chamber 37.

In some cases it may be found desirable to provide an upwardly openingcheck valve 88 in the air pipe 85 above the valve 86 and a downwardlyopening check valve 89 in the steam pipe 82 above the T 83, although notordinarily needful.

The operation of the device is as follows: The tank 1 of the reservoirhaving been supplied with water, oil and air under pressure, the valve80 is opened permitting the oil to fill the retort and flow by means ofthe pipe 87 to the chamber 37. The valve 86 is then opened to admitcompressed air to the chamber 39 and by operating the shaft 66 or bydirect application of the hand to the disk 62, the valve 48 is retractedwithin the casing 36 so as to withdraw said valve from its seat 46 andpermit the oil to flow from the chamber 37 through the nozzle 45. Itwill be noted from an inspection of Figs. 6 and 7 that the threadedconnect-ions between the valve 48 and the casing 36 at 38 is by a righthand thread, while the engagement between the valve 57 and the exteriorvalve 48 at 58 is by a left hand thread. As the valve disk 62 and thevalve 48 are rotated anti-clockwise to open the same, a relativecontra-movement is imparted to the valve 57 by reason of its left handthread and from the fact that it is held against actual rotation by thepin 73, thus the opening of the valve 48 operates simultaneously to openin a corresponding degree the valve 57, the ratio of such openingdepending upon the relative pitch of the threads at 49 and 58. Therelation between the two valves is also made adjustable by the positionof the plurality of sockets 72 for the alternative reception of the pin7 3. The oil is by the compressed air atomized at the nozzle 45 andinjected through the fuel inlet 29 into the burner 27. At this time theburner valve 33 is removed from the opening 32, so that gas on beingignited burns at the opening 32 immediately beneath the retort. As soonas the retort becomes sufficiently heated water is admitted theretothrough the pipe 74, which flashes into steam and is conducted by thepipe 82 to the chamber 39, where it takes the place of compressed air,which is then shut off by the closing of the valve 86, and the supply ofoil to the chamber 37 is substituted by a supply of gas as the oilwithin the retort chamber 29 becomes vaporized. Thereupon the valve 33is closed by its stem 34 and thereafter the gas injected into "saidburner by the 'steam is burned in conjunction therewith at the slots 28,the combustionv being practically perfect and resulting in an intenseheat available for use in the heatingofa room by means of the fluel-2and drum 9, or the device may be placed within a stove or the likeand employed to heat articles above the same. 4

It will be understood that while the draW- ings illustrate a practicalform of the invention, the latter is susceptible of various changes andmodifications so long as such changes do not mark any material departurefrom the salient features of the invention.

In Fig. 9 is shown a modified form of retort, wherein the body 13 isdispensed with and the upper water chamber 75 is replaced by a watercoil 7 5 fed by the water pipe 82 and in turn supplying the steam pipe74. The oil vaporizing chamber 79 is also in this case substituted bythe oil vaporizing pipe 7 9 which is fed by the oil pipe 78 and suppliesin turn the gas pipe 87 The steam pipe 74* leads by way of the pipe 843to the steam chamber of the jet device 35 and the gas pipe to the gaschamber as in the former case.
